THOMAS ANGELL, OF BROOKLYN, NE\V YORK.

GAS-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 310,240, dated January6, 1885.

A pplicalion fi ed June 9.2!, 1894.

To aZZ whom it may concern:

Be it known that I, THOMAS ANGELL, of Brooklyn, inv the county of Kingsand State of New York, have invented an Improvement in Gas-Regulators,of which the following is a specification.

Gas-regulators have been madein which the valve that regulates theadmission of gas is connected with an inverted cup, the edges of whichpass into an annular holder containing mercury. The parts, however, areconstructed in such a manner that the gas flows through the chamberwithin the inverted cup, and there is risk of accumulation of water andother products of condensation in the said chamber. Besides this, thegas-regulator 0ccupies so much space between the meter and the pipes inthe building that changes are often required for allowing the regulatorto be introduced.

In my improvement the inletpipe for the gas is in line with theoutlet-pipe, and there is but little space occupied, so that usually theregulator can be introduced by simply springing the pipes apart. Theregulator is at one side of the couplings, and it is constructed so thatthe gas passes from the valve directly to the discharge-chamber througha valve-seat, which is screwed into the partition, and is, with thebridge that guides the valve-stem, removable upwardly, so that the partsare. easily cleaned, and the gaspipe connections are not disturbed.

In the drawings, Figure 1 is a vertical section of the regulator, andFig. 2 is a plan with the cover and part of the inverted cup removed.

The cylindrical case A is made with a lateral double chamber passing offfrom the center of the case A. The diaphragm or partition B is betweenthe chambers c and (l, and within the lateral case E, and this case Eprojects beyond the case A a sufficient distance to receive the couplingj, that connects the regulator to the meter, and the coupling g, thatconnects theregulator to the pipes of the building. These two couplingsare in line with each other, so that the connection for the regulatorcan be made by springing the pipes apart a sufficientdistance Forintroducing the (Kn model.)

regulatorcouplings. The couplings f and are screwed directly into themetal of the case E, and can be removed so as to introduce whatever sizeof coupling may fit the unions upon the meter and pipe, respectively,thus allowing for fitting the same regulator upon any metenpipesbysimply changing the couplings f and g,- and as these couplings screwdirectly into'the top and bottom plates of the case E, and astheseplates extend all around theholes into which the couplings screw,said holes can be made larger or smaller to suit different couplingswithout changing any of the parts of the regulator, and the couplingscan be introduced in a very small space and lessen the distance that thepipes have to be sprung apart to introduce the regulator. The diaphragmB completely separates thechambers c and (7,

except that in line with the center of the case A there is an opening,into which is screwed the ring-seat h for the valve It. The stem 1' ofthis valve 7: passes through and is guided by the bridge Z, that risesabove the valve-seat, and this stem passes through the center of theinverted cup at, and it is secured thereto and adjusted by the loelcnutsit upon such stem 2. The inverted cup at is preferably made of thinsheet metal, and its cylindrical rim is within the annular troughcontaining mercury at 0. The dams and q are concentric within the caseA, and thendam 12 forms one side of the annular mercurytrough. The dam qextends up to near the under surface of the inverted cup m and itsobject is to catch any mercury that may be spilled over from the trough0, and prevent it passing down into the meter, also to lessen theopportunity for gases or watery vapors to pass into and circulatethrough the chamber below the inverted cup m. The gases pass from theinlet-coupling f along through the chamber 0, and through the valveseat,and then directly off by the chamber (Z to the coupling g and pipe. Theairand gases inside the inverted cup remain almost quiescent, but theyare subject to fluctuations in the pressure. \Vhen the burners are shutoff and the gas accumulates in the chamber (Z, the inverted cup islifted and the valve 7.: closed, or nearly so. XVhen the pressure in thechamber (1 lessons in consequence of the burners being opened, theinverted cup descends and opens the supply-valve in proportion to theamount of gas that is being consumed. Should there be any water ofcondensation in the pipes of the building, or in the gasregulator, itpasses directly through the regulator and into the meter, and cannotaccumulate in the regulator or obstruct the flow of gas, and no plug orcock to draw off such accumulation is required.

A cover, 8, may be applied to the case A of the regulator to excludeforeign substances.

I do not claim a gas-regulator with alateral case containing a partitionwith a valve-scat. In some of the regulators of this character the valvehas to be removed downwardly and the inverted cup upwardly. In othercases the seat was removable, but not easy of access, or in thepartition. In consequence of the valve-seat being provided with thebridge Z, that extends upwardly and guides the stem, the seat, whichotherwise would be difficult of access, can be unscrewed by means of thebridge, and the valve-seat and valve are removable upwardly after theinverted cup has been taken 01?, so that the regulator only requires tobe opened on top in obtaining access to all the parts.

I claim as my invention-' 1. The combination, with the case A, of alateral case, E, with a partition in it, an upwardly-projecting bridge,and a valve-seat screwed into an opening in such partition, a valve andstem, an inverted cup attached to and removable from the valve-stem, anannular mercury-trough within the case A, and a dam, also within saidcase, whereby the valve and its seat maybe removed after theinverted cuphas been taken off the stem, substantially as specified.

2. In combination with the gas-regulator and lateral case E, having apartition and valve-seat, the removable and changeable couplings f andg, in line with each other, and screwed into openings in the flat topand bottom plates of such case E, substantially as set forth.
